Among the numerous π-donor molecules described in the literature as precursors of organic materials various heterocyclic derivatives have been studied, mainly conjugated frameworks including sulfur atoms, such as tetrathiafulvalene (TTF). 1 Several modifications of the TTF skeleton have been performed, for example replacement of two sulfur atoms by nitrogen atoms has led to dithiadiazafulvalene (DTDAF) derivatives which have recently attracted attention owing ...
